Windows 7: SP1 fails to download

I really don't know... You don't really hear the success stories, and most people that can't get it installed can't be bothered, and really don't care enough to pop over to Sevenforums to ask. It's a tough one to judge really.

I remember XP SP2 giving me crazy headaches. I finally broke down and re-installed. It was my first reformat actually. So I learned some basics from it.

Vista SP2 was painless for me, installed from WU without a hitch, but I ended up doing a clean install anyway. I think I was bored or something.

I've already done one clean install and was hoping to avoid doing another. That said,it's beginning to look like that is my only option or I will just continue to have problems going forward . Sure hate to loose all those little tweaks ...
So if I understand you correctly and want to go that route. Clean install win7, run RUS from the copy I downloaded, run SP1 from the copy I downloaded. The run windows update for all else?
Would it be wise to run a repair from the original win7 disk first just to see if that takes care of the problem or would that just be a waste of time?

You won't loose everything. Drivers and such stay so no need to redo them.
I would back up everything.
It all should be there when done with repair install.

Some people have fixed the problem with repair install.

Anyway if everything is backed up you will be ready for reinstall if necessary.

I'm not suggesting or telling you to do either it is what I would do first- repair install at this point- if all else has failed.
Up to you.
Those are the options if you decide to .

After deleting SoftwareDistribution Folder SP1 will partially download from Windows Update. Stops at 33% and gives same error 800b0100.
Strangely standalone installer still does nothing just gives same error.
ps I have done every suggestion put forward sofar re install problems.
My issue is that unless this is resolved without reinstalling the same issues will arrive down the track with other SP's or major updates.

If you receive the Windows Update error 800b0100, it means that a file needed by Windows Update is not registered with Windows correctly.

You could look at the CBS.log to see if there is an update that shows with an error and, if it is uninstallable, remove it, reboot, install it again, reboot and then try the SP again. You need to copy "C:\Windows\Logs\CBS" to your document folder and then open the log with Notepad.

Otherwise, I would opt for the repair install first to see if that is successful. Another option is that free unlimited installation and compatibility support is available for issues related to Windows 7 Service Packs. Availability of chat, phone or e-mail support differs depending on your geographic location. Some issues may require more advanced support for which there may be a charge. (Note: If you select Other, please have your Product Identification Number available as it will be needed to determine if no-charge support is available)

It will be helpful to provide "C:\Windows\Logs\CBS". Zip all files into 1 ZIP file. If the zip file is too large to attach to your support request, upload the zip file to your SkyDrive and include the file name and link in your support request.

After you install Windows, just throw the SP1 straight on it. Make sure you're connected to the net when you do this. The SP install process will download the files you need.

Dear electrotune 1200,
Amen! The best advise so far and a rep+ is winging your way from me! The central point which has to be understood is"throwing the SP1 right into the pristine new re-formatted disk with the OS cleared of all junk!"

I bit the bullet and cloned my hard drive so that I had a fully functioning backup. Did an update install then ran standalone SP1 installer then went to windows update, only about 9 to download. Deleted all install backup files had to reinstall video drivers, finished with big defrag. All is working perfectly now.
The End!!
